ANDREVI VAKULA, OF CARO, MICHIGAN.

PORTABLE FENCE.

Application filed June 5, 1914. Serial No. 843,170.

To all whom it may concern:

Be it known that 1, ANDREW VAKULA, a citizen of the United States, residing at Caro, in the county of Tuscola and State of Michigan, have invented certain new and useful Improvements in Portable Fences, of which the following is a specification.

This invention relates to certain new and useful improvements in portable fences.

An object of the invention is to provide a fence formed of a plurality of foldable sections which may be easily and quickly set up in operative position and effectively held rigid.

A further object of the invention is to provide a fence formed of a plurality of foldable sections so that the same may be mounted over level or uneven surfaces and further permitted to be set up at any desired angle.

A further object of the invention is to provide a portable fence formed of a plurality of foldable sections in combination with a plurality of roller trucks adapted to operate in connection with the fence when the same is being folded together with an operating rope for causing the sections to fold with a lazy tong movement.

With the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described and then claimed.

In the accompanying drawing which shows the preferred embodiment of my invention and to which reference is had herein by like characters designating corresponding parts throughout the several views Figure 1 is a side elevational View of the fence in set up position. Fig. 2 is a side elevational view of a portion of the fence showing the wheeled carriage in position while the fence is being collapsed. Fig. 3 is a vertical cross sectional view showing the carriage in position beneath the fence. Fig. 4 is a side elevational view of the rod connecting the sections, and Fig. 5 is a perspective view of a portion of one of the foldable sections.

Briefly described, the invention comprises a plurality of collapsible fence sections, each section being of any suitable length and comprising the usual cross wires with eyes formed at each end of the longitudinal strands. The

Specification of Letters Patent.

Patented Dec. 22, 1914.

meeting eyes of the longitudinal strands are positioned as shown in Fig. 2 and passing through the said eyes is the bolt shown in Fig. 4 on which the sections pivot to adapt the same to be folded or cause the fence to assume any desired angle. Brace rods are provided at each end of the fence by which the same is securely fastened to the ground. I further provide a plurality of wheeled carriages operating in connection with the foldable sections to cause the same to move freely over the ground. and in no way present a binding action, the fence being collapsed by a rope or other similar means in the manner to be hereinafter described.

Referring more in detail to the accompanymg drawing, there is shown a fence formed of a plurality-of foldable sections,

each section comprising any number of longitudinal strands 10 having formed at each end thereof a horizontally disposed eye 11, and extending transversely of the longitudinal strands and secured thereto by the conventional electric weld are the vertical strands 12. In the position shown in Figs. 1 and 2, as assembled, the eyes 11 of the strands 10 register with the eyes carried by the adjacent fence section and passing through the registering eyes 11 are the bolts 13 headed at their upper ends as at 14 to limit the downward movement thereof to prevent the same from entirely passing through the registering eyes. These bolts 13 are threaded at their lower ends as at 15 and have the threaded ends thereof received in the threaded sockets 16 formed in the upper face of the ground plugs. 17. As shown in Fig. 1, I have provided means for holding the sections in extended position, such means consisting of guy wires 18 having their lower ends 19 hooked to engage the ground while the upper end is provided with an eye 20 to be received on the bolt 13, thereby holding the fence sections in a stretched rigid condition.

Several of the fence sections at desired spaced intervals are provided with means operating in connection with the wheeled carriage to assist the fence in its movement over the ground, while the same is being collapsed, such means comprising in detail as shown in Fig. 3 a bar formed of a pair of sections 21 secured together by the bolts 22 and suitably grooved to provide seats for the longitudinal wire strands 10. The lower end of one of the bars 21 is provided with a socket 23 for the reception of a pin 24: carried by an angle member 25 supported on the wheeled carriage frame 26. A roller 26 is mounted on each end of the carriage 26 and which rollers are so disposed as to prevent the fence from falling over. A rope 27 is connected at one of its ends to one of the end bolts 13 of the end fence section and passes in front and back of the alternate bolts 13 of the fence, passing through guiding eyes 28 carried by the bar 21 and when manipulated adapted to cause the several fence sections to collapse by the lazy tong movement.

As shown in Fig. 1, the fence is set up in its usual operative position with the guy wires 18 stretching the same and holding it into fixed position relative to the ground, with the bolts 13 threaded into the socket ground plugs 17. The bolts 13 pivotally connect each of the sections and it is to be noted that the fence may be caused to assume any desired angle at the joint and at such angle, a supplementary guy wire 18 may be provided and used in the manner similar to the end guy wires to reinforce and brace the angle of the fence.

hen it is desired to collapse the fence the wheeled carriages 26 are moved into position as shown in Figs. 2 and 3 with the pin 24 carried by the carriage frame 26 re.

ceived in the socket 23 in the lower end of the bar 21. The bolts 13 are then turned to disconnect their lower ends from the threaded socketed plugs 17. One of the end guy wires 18 is then released and any guy wires intermediate the ends are also released after which, manipulation "of the rope 27 will cause the fence sections to collapse with a lazy tong movement.

While the accompanying drawing shows the preferred embodiment of my invention, I do not wish to confine myself to the exact details of construction shown, as various forms, modifications and arrangements of the parts as shown may be had without departing from the spirit and scope of the invention as claimed.

What I claim as new is A collapsible and portable fence comprising a plurality of sections each consisting of vertical wires and longitudinal wires the latter being formed with terminal eyes, to overlap and to register with the eyes of the next adjacent section, headed bolts extending through said registering eyes, to hinge the sections together and threaded at their lower ends, internally-threaded ground plugs to receive the threaded ends of the bolts, a plurality of bars each consisting of sections grooved on their inner sides to receive said longitudinal wires, and one of said sections having a socket at its lower end, means for securing said bar sections together, a flexible connection secured at its ends to the end bolts of each section and extending alternately on opposite sides of the intermediate bolts of the section, and a wheeled carriage having an upwardly projecting pin fitting the sockets of the bars.

In testimony whereof I aliix my signature in presence of two witnesses.
